To all 'whom t may concern, Y

Be it known that I, WILLIAM G. BRIGGER, a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Water-Motors, of which the following is a specification, reference being had therein to the accompanying drawing.

The invention relates to watermotors and has for its object to provide a motor of this character wherein the piston of said motor is reciprocated by fluid supplied and passing through said piston under pressure.

A further object is to provide a water motor of this character wherein water is admitted under pressure to a chamber of the piston, thence through a hollow valve stem to a chamber formed by'a casing on one face of the piston and thence into one end of the cylinder, said passingy of the iiuid through the chamber of the casing closing a vvalve transversely disposed in the piston and at the same time opening an exhaust port on the other side of said piston thereby allowing the fluid in the other end of the cylinder to pass into a chamber of the piston and thence discharge through the piston rod at the opposite side to the intake.

A4 further object is to provide each chamber of the piston with opposite registering ports, said ports having slidably mhunted therein valves adapted to coperate with valve seats at said ports, one of said slidable valves forming an exhaust valve on both strokes of the piston and theother valve forming means for directing the fluid under pressure to either side of the piston accordthe direction in which the piston is moving. Also to provide housings having ports therein on the faces of said pistons, and arching the ends of the slidable valves, and toslidably mount in saidhousings pilot valves, which pilot valves are adapted to engage the cylinder heads,therebyv moving the intake'control valve longitudinally at the vends of the strokes-so'as to reverse the direction of reciprocation ofthe piston.

With thel above and other objects in view the invention resides in thelcombination and arrangement of parts as hereinafter set forth, shown in the drawings, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the Spirit of the invention, i n Y In the drawings Figure l is a perspective view of the'water i motor showing a conventional formofuse of the motor for driving a washing machine. Fig. 2 is a horizontal sectional view taken on line 2-2 of Fig. 41, showing the pistonin elevation.

Fig. 8 is a perspective view of the intake control valve;

Referring to thel drawings, the numeral 1 designates a cylinder, and 2 and 3 the cylinder heads, said cylinder heads being provided with packing glands' 4. Disposed in the cylinder 1 and adapted yto beureciprocated therein is a piston 5, which piston is provided with a conventional form of pack-y ing 6 for preventing the leakage of water from one side of the piston to the other side. The piston-5 is hollow and is kdivided into compartments 7 and 8 by means ofa diagonally disposed wall 9. Threaded into one side of the piston 5 is a pistonVv rod 10,V

which piston rod is hollow and is provided with an intake4 passage 11, whereby water under pressure is conducted to the: chamber 8, said piston rod v10 reciprocating Vin the packing gland 4 and within' an intake pipe.

12 to which any suitablewater supply pipe may be coupled as at 13.

A discharge pipe 14 which forms a piston rod is threaded into the oppositev wally vof the piston and preferably in aXial alinement e with the intake ing chamber 7 of the piston. The side walls of piston rod, its inner end bel the piston are provided with ports 15, which ports are in communication with the discharge chamber and have slidably mounted in said ports a valve 16, which `valve istri-Y angular in cross section and is provided with headed kmembers 17. forming valves, adapted sides ofthe piston so as to admit and prevent the entrance of fluid'into the discharge chamber according tothe direction in which the piston is moving.

piston, at opposite sides of the intake chamber 8, said valve 18 being provided with a central solid portion 20, having on its opposite faces ground surfaces 21 whichare adapted to cooperate with seats22 and 23.

"The seat 23 is carried by a bushing 24, which Y bushing is threaded into one wall of thepiston, said bushing being provided for the purpose ,of allowing the enlarged central portion ofthe valve to be placed within the chamber 8. It has been found that during` the grinding and turning of the intake valve 181and also during the assembling of the valve that the -valveseats thereof vary in relation to their distances from the ends of the valve, hence whenl assembling the valve it is necessary thatV the val-ve be not put into To avoid this dii'iiculty, the portion of the valve vthat has a bearing inv the bushing 24 is preferably of a larger diameter than the end 25,Y so that it l' will be impossible when assembling' the ment with the valve partsnto get the valve end for end. The portion 25 and the portion l26 are cylindrical and hollow and are provided with ports 27 so that water may be admitted to the hollovs7 ends of the valve when said ports 27 are uncovered, Ends 25 and 26 project beyond the faces of the piston and are adapted to. bel cooperated with by pilot valves 28 and 29, 'which are in axial aline- 18 and are slidably mounted ingbearings 30 of housings 31, which incase the ends of thev valves 16 and 18 and are in communication with the ends Vof the cylinders by means of ports `32. The

passages throughy the housings provide means whereby the force,A of the water is applied ydirectly to the endsof the valves 16, thereby causing the action of the same to be immediate and positive, which is not the case where thewater enters the end ofthe cylinder, then exerts its pressure between the cylinder head and the end of the exhaust valve.

The outer end of the discharge piston 14 has threaded thereon as at 33 a rack 34,

v which rack is adapted to engage a pinion 35 which is keyedlor Votherwise secured on a downwardly Vinto a washing machine'37, and may have shaft' 36, saidvl shaft extending securedv thereto any conventional form of agitator. The discharge piston discharges into an integral hollow lug 38, to which may be attached a hose, so thatthev waterV as it passes through the motor and is discharged'therefrom may beconveyed to a sewer or 'other' pointof discharge.

The operation is as follows, the water enters through the piston rod 10 and enters the chamber 8, then it passes through the end 26, of the valve 18 exerting a pressure against pilot valve 29', reversing valve 18 to its opposite seat, then it passes through the 'chamber-of the housing directing a direct inlet valve comprising p I Y ends hollowed and its central body enlarged, Y

pressure on the head of valve 1,6 therebyl closing the sameV and then the-water enters the end a through the port 32, said water I valve to opposite seatallowing the wateri i under pressure to rush out- 'and' into the the Vhousing lchamber pressure Von the head 17 of the exhaust'valve 16 before water pressurev escapes'into endbn of the cylinder through port 32. From the above it will be seen that the exhausting'of water fromthe end b ofthe cylinder will be cut oiil and that the head l'r'pof the valve 16, will *uncover the exhaust port 15 on the other side ofthe piston so that'the water in the end a of the cylinder may pass through the port 15 into chamber 7,thence through piston 14 to its linal discharge point.` The discharging may 'i Y operation of intaking and be continued and the piston caused to reciprocate within the cylinder.` In the various figures kthe arrows in fulllines show the course of the water tothe driving Vside of vthe piston, thoseY in dotted lines show thecourse of the water as' it exhausts afterperforming its function of driving thepiston,l

'It will be seen that a structure' is provided wherein the action of,Y theI parts isY positive, andwherein the working parts are reduced to a minimum. f

The inventionV having beeny set forth what is claimed as new and useful is l' 1. In a'mo'to'r of the character described,
